Abstract: A brake control apparatus includes a bracket (3), a brake lever (4) pivoted to the bracket via a lever shaft (5) and a lever spring (6) for urging the brake lever to its home position relative to the bracket. The lever spring has first and second spring legs (62,63) engageable respectively with the bracket and the brake lever and a coil portion (61) disposed between the first and second spring legs. A return movement of the brake lever to its home position relative to the bracket is realized by flexion of a radial center line of the coil portion of the lever spring. With this control apparatus, the lever spring can provide substantially constant urging force regardless of the pivot amount of the brake lever and the lever spring does not produce unpleasant creaking noise in the course of a braking operation.

Abstract: A xerographic copying machine (100) has a circulating endless belt photoreceptor (1). A toner image is transferred from the photoreceptor (1) to a copy sheet (26) at the transfer region (5). The sheet (26) is fed to the transfer region (5) by a pair of coacting rolls (26) driven by a variable speed stepper motor. The rolls (26) feed the leading portion of the copy sheet at approximately the same speed as the photoreceptor. When the copy sheet (26) contacts the photoreceptor (1) the feed rolls (26) are driven at a faster speed for a short interval to generate a buckle (B) in the copy sheet just before the transfer region. The speed of the feed rolls (26) is then returned to its initial value so that the buckle size remains constant while the remainder of the sheet is fed. The buckle (B) provides sufficient surplus in the copy sheet to prevent it being pulled taut in the transfer region (5). This prevents smearing the unfused toner image. Also, the buckle (B) bears against the concave guide surface of guide member (18) which acts to stiffen the copy sheet in the process direction at the transfer station. this helps to reduce the tendency for any post-transfer lead-edge "shocks" from propagating back to the transfer station which can also cause image smear.

Abstract: In the operative position shown in Figure 4 a printing roller 138 abuts the cylindrical surface of an impression roller 10 to cause ink to be transferred from an anilox roller 144 via the printing roller 138 to the impression roller 10. The gear wheel 134 on the impression roller 10 meshes with a gear 140 on the printing roller which in turn meshes with a gear 142 on the anilox roller to cause rotation of those three rollers. 
     The printing roller and the anilox roller can be moved to the right, when viewed in Figure 4, to move their co-operating cylindrical surfaces out of contact with each other, and yet still leave their gears in mesh in order to enable the printing roller to be changed and yet maintain the rotation of the anilox roller 144. A clutch is provided to enable the printing roller to be stationary when being changed, or to enable the printing roller to be correctly aligned with the impression roller when brought back into co-operation therewith.

The incubated blood is then drawn into a transparent tube containing a float which concentrates the buffy coat constituent layers upon centrifugation of the blood sample. The concentrated lymphocyte layer is then examined for fluorescence or coloration which is indicative of the presence of the activated lymphocytes or lymphoblasts, and their concentration. The fluorescence or coloration can be qualified and/or quantified by a reader instrument.

Abstract: A quasi-achromatic configuration of two Faraday elements (85, 87) and five birefringent plates (86, 88) which when suitably oriented between two linearly polarizing elements (84, 89) would constitute an optical isolator or circulator. The nominal Faraday rotations of the two elements are 45° and 90° at a center design wavelength about which the devices are to operate. Changes in these rotations due to either wavelength or temperature variations compensate one another because of their coupling by the birefringent plates. In this way a higher degree of isolation is obtained over a wider optical bandwidth than would be possible in a device using a single 45° Faraday element. A group of three plates (86) is used between the two Faraday elements (85, 87) and two more (88) follow them to give the required polariza­tion transformations which must themselves be quasi-achromatic over the desired wavelength range.
